1. A radio frequency module comprising:
- a module substrate;
an antenna element on the module substrate;
a tuning conductor on the module substrate and adjacent to and spaced apart from the antenna element, the tuning conductor operable to load the antenna element; and
a switch electrically connected between the tuning conductor and a ground voltage, the switch operable to selectively connect the tuning conductor to the ground voltage to control an antenna characteristic of the antenna element.

Abstract
Apparatus and methods for reconfigurable antenna systems are provided herein. In certain configurations, an antenna system includes an antenna element, a tuning conductor adjacent to and spaced apart from the antenna element, and a switch electrically connected between the tuning conductor and a reference voltage, such as ground. The tuning conductor is operable to load the antenna element, and the switch selectively connects the tuning conductor to the reference voltage to provide tuning to the antenna element.
